Changing the Master of Your Heart
Pastor Tan Thai · Jan 21, 2018
This sermon calls listeners to recognize that truly abiding in Christ requires a change of heart's master — surrendering control of one's life and inviting Jesus to be the true Lord. The pastor emphasizes that this transformation must flow from gratitude and love for God, not from fear or comparison with others.
This sermon is part of the series "Abide in Me" based on John 15:4, focusing on the second component of the prayer of faith: inviting Christ to be the true Lord of one's life. The pastor explains that the Church is built on the foundation of Jesus Christ, and to abide in Him, believers must change the habits of their heart — because those habits reveal what is most important in a person's life.
The pastor revisits two major obstacles discussed in the previous message: preoccupation with the flesh, which enslaves people to its endless demands, and self-deception — refusing to acknowledge one's own sin. The first step toward change is repentance and asking for God's forgiveness, just as the tax collector and the sinful woman did. The pastor cites 1 John 1:8-9 to affirm that sincere confession leads to forgiveness and cleansing.
The sermon's central section focuses on the second part of the prayer of faith: asking Christ to take lordship over one's life. Using the image from Revelation 3:20, the pastor explains that Christ does not merely come in for a meal and leave like a guest; He stays and becomes master of the entire house — including its most private rooms. Ephesians 2:12-13 and 1 Peter 3:15 are cited to highlight the transformation from being far from God to being brought near through Christ's blood.
The pastor emphasizes two crucial conditions: first, the decision to invite Christ as Lord must be voluntary, arising from gratitude and love — not fear of punishment. Matthew 11:28-30 and John 14:15 are referenced to show that the yoke of Christ is light and that obedience flows from love. Second, believers must keep their eyes on Christ, not on others, to avoid the traps of comparison and pride. The parable of the prodigal son (Luke 15) and the account of Peter by the Sea of Tiberias (John 21:19-22) illustrate both the danger of resentful comparison and the call to follow Christ personally.
The sermon closes with a practical call to take the first step in changing the master of one's heart. The pastor also connects the message to a contemporary social crisis — the epidemic of loneliness in modern Britain — noting that one in six people in the UK struggles with loneliness. He challenges the church to be a place of healing for the lonely, but stresses that this is only possible when believers allow God to reshape the habits of their hearts toward genuine compassion, citing Colossians 3:12-16.
